What blood types would your parents have to be to have a child with A positive blood type?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

What does plus and - stand for in blood group?
positive and negative stands for either Rhesus Positive or Rhesus negative which means that a persons Red blood cells (RBC) either have D antigens on their cell surface membranes or not. a person who is Rhesus negative will have D Antibodies in the blood plasma and can only be given Rhesus negative blood types in a blood transfusion. Rhesus positive blood types can be given either D+ or D- in a blood transfusion as they have no D antibodies in their blood plasma. hope this helps
Can the baby of an O rhesus positive and a A rhesus negative parent be A rhesus positive?
no cause a positive and negative make a negative unless the positive has a really strong blood line
What is the universal recipient in blood transfusions?
AB positive; a person with rhesus-negative blood can have an adverse reaction if given rhesus-positive blood.
Can blood be either B positive or negative?
Not exactly. Human blood may have positive (ca. 80%) or negative (remaining 20%) Rhesus factor. It means that that a substance known as Rhesus factor is either found or not in a human blood test. Transfusion of "positive" blood to a "negative" recipient may result in very negative consequences (but not vise versa) . A problem known as Rhesus conflict may arise when a Rhesus-negative woman is pregnant with a Rhesus-positive baby.The name Rhesus factor comes from Rhesus monkey in which it was first found.
What is reses negative?
If you mean Rhesus - it's a classification in blood groups of a lack of Rhesus anti-bodies.
Is there a problem for the baby when the father is rhesus negative and the mother is rhesus negative?
No.there is no problem.Because both male and female are unable to produce rhesus antigen and there is no prouction of antibody inside the baby blood.
What is the difference between negative and positive blood type A?
The Rhesus factor, also known as the Rh factor, is an antigen that exists on the surface of red blood cells. People who have the Rhesus factor are considered to have a positive blood type. Those who don't have the antigen are considered to have a negative blood type.
How many blood types are there how blood type is inherited?
To the second question the answer, in short, is YES; To answer the first question, there are four logical blood types: A, B, AB, and O. Then there is the Rhesus factor: either positive or negative. So there are actually eight types of blood a human can have: one of the above types with a negative Rhesus factor or with a positive Rhesus factor. Rhesus factor is a factor which compares human blood to a Rhesus monkey's blood. A negative result means your blood is not comparable to a Rhesus monkey. Blood types are inherited from your parents. If one parent has type A+, and the other has a B-, your blood type can either come out as A, + or -, or B, + or -, or the rare AB, + or - but not O. While type O negative is the universal donor, type AB positive is a universal recipient.
Why does haemolytic disease of the newborn not occur in rhesus positive mothers with a rhesus negative baby?
HDN only occurs in rhesus negative women who have been sensitized by positive blood. Rhesus positive mother can have a rhesus negative baby. In rhesus positive group, they have the antigen Rh. When this antigen from baby enters mother's blood circulation, because of inutero bleed in pregnancy; mother's blood cells will react to the foreign antigen and produce antibodies which are harmful to the baby's blood cells when they cross the placenta and enter baby's blood stream. These antibodies will break baby's blood cells down causing haemolytic disease. Whereas in rhesus positive mother with negative baby, if baby's blood enters mother's circultaion it will not produce any antibodies as there are no antigens in Rh negative blood. And if mother's blood mixes with baby's blood in the womb, baby will not have the ability to produce antibodies as their immune system is not developed. So there is no chance for haemolytic disease.
How common is blood type a negative?
No, only 7% of the world has O negative blood type.We couldn't say our blood type a negative without testing.It has been found that the most common blood types are the Rhesus factor positive or all the positive blood types like A+, B+, AB+ and O+. When compared with their respective negative counterparts, the percentage of the positive blood types is more than that of the negative ones. That is, nearly 85% of the world population have Rhesus positive blood type, while only a mere 15% have Rhesus negative blood type.
